Bpoletti, the correct amount of oil will stay in the well, and not work it's way out of the well. No need for your "oil trap". A tip:
A few years ago, after cleaning and relubing my TNT bearing, I was dismayed at what initially seemed like boring, unexciting sound; or as some would say, no PRAT. Turned out that I had put too much oil in the well. The excess oil had accumulated around the top of the bearing well's circular top plate, and was making contact with the bottom of the platter spindle's circular bottom plate. As the platter turned, the excess oil was putting drag on it. The sonic effect was not subtle. Beware of too much oil (or grease).
